CHARLES J. FISH, OF SEATTLE, WASHINGTON.

AUTOMATIC SHUT-OFF.

T 0 all whom it may concern:

Be it known that I, CHARLES J. FISH, a citizen of the United States ofAmerica, and a resident of the city of Seattle, in the county of Kingand State of Vfashington, have invented certain new and usefulImprovements in Automatic Shut-Offs, of which the following is aspecification.

My invention relates to apparatus of the above type, having particularreference to an apparatus of this character wherein the weight of thematerial or fluid fed or discharged is applied to operate the shut-ofl'means, and has for a fundamental object the provision of a novelconstruction wherein a receiving receptacle is connected with theshut-off mechanism for operating the latter to its closed position bygravity.

Other objects will be set forth as my description progresses, and thosefeatures of construction, arrangements and combinations of parts onwhich I desire protection, succinctly defined in my annexed claims.

Referring to the accompanying drawing, wherein like numerals ofreference indicate like parts throughout: Figure 1 is a vertical sectionof a preferred embodiment of my invention. Fig. 2 illustrates myinvention as in use, the same being connected with a pipe which may bein communication with a source of supply at a remote point, and Fig. 3is a perspective of my device connected with a suitable supply tank, thelatter being shown fragmentarily.

In this the preferred embodiment of my invention, I provide a flexiblefeed tube 1, the same extending between opposing jaws 2 and 3, whichlatter are free for movement toward and from one another to therebycontrol the delivery through tube 1. Jaws 2 and 3 are connected withrespective spring arms 4 which serve to return and hold the same intheir open positions.

Reference numerals 5 indicate arms projecting outwardly from jaws 2 and3 and connected, as by links 6 with a receiving receptacle 7 extendingbeneath delivery member 1.

My invention is designed primarily for maintaining a constant andsubstantially uniform fresh supply of drinking water for young fowl, andas now constructed can be readily applied to brooders. I do not howSpecificationof letters Patent.

ever, desire to be understood as limiting my invention to thisparticular application.

As now considered, arms 5 comprise the free end portions of astrip ofspring sheet metal which at the inner end portions of said arms is givena reverse bend to provide the jaws 2 and 3 and then bent tosubstantially circular form to provide the arms a which, as shown, areunited at their upper end portions and suitably apertured for receptionof a nipple 8 of a coupling member 9 adapted to be connected with asuitable source of fluid supply, as for example, a tank 10 or supplypipe 11. Coupling member 9 is formed with a shoulder 12 on which theshut off mechanism is clamped by a suitable nut, as 13.

Reference numeral 14 indicates a guard for the lower end portion ofdelivery tube 1, the same being carried by one oft-he arms 5 andreceiving said tube so as to protect the same against injury by thefowls, as will be readily understood. I

In the operation of my invention, spring arms a will open jaws 2 and 3as the weight or quantity of fluid in receptacle 7 is decreased, therebypermitting of member 1 opening for passage of fluid from the source ofsupply therethrough.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States of Amer- 1ca, 1s:

1. In apparatus of the character described, opposing jaws a flexibledischarge means extending between said jaws, a support for said jawshaving a depending spring arm carrying one thereof and tending to holdthe latter in its retracted position, and a suspended receptacleconnected with said last named jaw for closing the same through theweight imposed by the material received from said discharge means.

2. In apparatus of the character described, a flexible discharge means,means for shutting off said discharge means through compression of thesame comprising opposing jaws, means yieldingly holding saidjaws inretracted position, and a receptacle suspended from said jaws forclosing the same through the weight imposed by the material receivedfrom said first means.

3. In apparatus of the character described, opposing jaws, a bowedresilient Signed at Seattle, Washington this 7th connecting member forsaid jaws, a flexible day of November 1911.

dischar e means extendin between said jaws, o utwardly projecting armsto said CHARLES FISH jaws, a receiving receptacle arranged be-Witnesses:

neath said discharge means, and means for ARLITA ADAMS,

suspending said receptacle from said arms. CLARA A. HARM.
